FINALLY found all the documentation I need to fix my laptop screen.

Tired connecting a data transfer wire I got, but it only shows the "host" CPU. No idea why.

They said it was OK to send it without the hard disk, so that's what I will do.

In the meantime, I resolved my issue of not seeing the screen. Got the laptop connected to my HDTV via an HDMI cable. The trick seems to be it has to be plugged in and not running off battery.

Currently moving 1,882 video files consisting of 392 Gb. I had no idea I had that much on that PC. I thought I moved most of it already. Likely just copied instead of cut. Or maybe there was a folder that I neglected and proved to be the "vein" in this video mine.
